It's been a few weeks since I got X running on z2buntu. These are the steps I went thru to get it to a usable state. You can install any window manager/desktop you want, but I went with matchbox and lxpanel (not full lxde). I hope I haven't forgotten anything.
Run the following commands:
apt-get install xserver-xorg lxpanel matchbox-window-manager matchbox-common op rxvt
chmod +x z2mouse-option
edit (or create) with sudo /etc/X11/xorg.conf and add
Option "fbdev" "/dev/fb0"
Option "Rotate" "CCW"
delete (or backup) then edit with sudo /etc/op/op.conf
shell /bin/su -;
